 I was going through the technical document "MC13211/212/213/214 Technical Data, Rev. 1.1", at page 27, section 5.2.3, its mentioned like this :-

A separate self-clocked source (approximately 1kHz) for the real-time interrupt allows a walk-up from Stop2 or Stop3 Modes with no external components. ,

Please confirm, that I wouldn't need any additional hardware circuit (low freq crystal) when i want to wake up the device from deep sleep modes after a long duration. (say, 300  seconds). What is the mechanism of waking up the device from deep sleep modes ?

best regards
